Improvement in water-coolers and refrigerators



UNITED STATES PATENT OFFICE...

JOSEPH HINDEMYER AND CHARLES C. dSAVERY, OF PHILADELPHIA, PA.

IMPROVEMENT IN WATER-COOLERS AND REFRIGERATORS.

Specification forming part of Letters Patent Nol 93,302, dated August 3, 1869.

.To all whom t may concern:

Be it known that we, JosEPn HINDEMYER and CHARLES C. SAVERY, of the city of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Water-Coolers and Refrigerators Combined; and we hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and to the iigures and letters of reference marked thereon.

The nature of our invention consists in the combination and arrangement of parts, as hereinafter more fully described.

In order that our said invention may be fully understood, we will now proceed more particularly to describe the same.

On reference to the drawings making part of this specification, and in which similarletters of reference allude to like parts throughout, Figure l is a sectional elevation of our improved cooler and refrigerator combined, and Fig. 2 is a sectional plan through theline x y, Fig. l.

A is the inner vessel or icereceptacle, which, in our usual construction of these coolers, is enameled on both the inner and outer surface.

B is the vessel which forms the outer portion of the annular surrounding-chamber, and is therefore enameled on its inner surface. The two vessels A and B are tightly jointed at the top, so that the space C between the two may hold the liquid under any usual degree of pressure without leakage.

D is the cock communicating with the inner chamber, and serves to draw from it the Waste or ice water. Y

E E are thecocks by means of which the liquid is drawn from the annular chamber C, and F is a small plug-valve for the escape of air from C in charging the same with the liquid to be cooled.

Gr is the supply-pipe to C. It is fitted with a stop-cock, H, and terminates near the top of chamber C, so as to cause the warm liquid to enter at the top when any of the cooled liquid is drawn off near the bottom at E E.

In the annexed drawings the improved cooler is shown in combination with a refrigerating-chamber, I, communicating with the outer air-space, K of the cooler in such amanner that the cold air may freely descend from thelatter into the refrigerating-chamber beneath. Vhen, however, the refrigeratingchamber K is dispensed with and the cooling action of the ice-chamber is to be expended onlyon the surrounding liquid in the chamber' C, then the spaceK is lled with any suitable non-conducting material.

Although zinc and other sheet metal may be used, on account of clieapness, in the` construction of the chambers A and B, it will "be observed that the oxidation ofthe metal must produce a more or less injurious effect upon the contents; and in order to obviate any unpleasant or injurious impregnation of the contents we have adopted the use of enameled cast-iron, in which the liquids retain their purity the same as they would inia porcelain or 'glass vessel.

Having thus fully described the nature and obj ects of our improved combination, what we claim as our invention, and desire to secure by Letters Patent, is

The ice-chamber A, annular space C, and surrounding air-space K, in combination with a refrigerating-chamber, I, the whole relatively arranged and operating as and for the purposes described.-
